Indications for Use

The device is intended for orthodontic movement of teeth. It is used temporarily and is removed after orthodontic treatment has been completed. The devices are intended to be single used only.

Device Story

Mach Brackets/Bright Brackets are orthodontic ceramic brackets bonded to teeth to facilitate tooth movement. Input: mechanical force from flexible orthodontic arch wires. Operation: brackets are bonded to teeth; arch wires are threaded through self-ligating mechanism to apply steady, gentle pressure to teeth. Output: controlled orthodontic tooth movement. Used in clinical dental settings by orthodontists. Benefits: aesthetic appearance, self-ligating design for easier wire placement/removal, and improved bonding/debonding characteristics.

Clinical Evidence

Bench testing only. Biocompatibility testing performed per ISO 10993-5 (in vitro cytotoxicity) and ISO 10993-10 (oral mucous membrane irritation and skin sensitization). All tests passed.

Technological Characteristics

Material: 99.99% translucent polycrystalline aluminum oxide (Al2O3). Form factor: orthodontic bracket. Mechanism: self-ligating ceramic bracket bonded to teeth, utilizing arch wires for force application. Sterilization: not specified. Software: none.

Indications for Use

Indicated for orthodontic tooth movement in patients requiring orthodontic treatment. Single-use only.

Regulatory Classification

Identification

JUN - 4 2012

## See 510(k) Summary, below.

Trade Name: . MACH BRACKETS , BRIGHT BRACKETS 1. Common Name: Orthodontic Ceramic Bracket Classification Name: Bracket, Ceramic, Orthodontic, product code NJM Product Code: NJM Requlation: 872.5470 Class of device : Class II.

- 1. The legally marketed device to which we are claiming equivalence: Orthodontic Ceramic brackets (K090933 )
### 2. Description of device:

The MACH BRACKETS are bonded to teeth to apply pressure to the tooth, transmitted through a flexible orthodontic wire, to alter the tooth position.

The modified orthodontic ceramic bracket has both aesthetic and self-ligating qualities. The modifications were aimed at facilitating easier orthodontic wire placement and removal through self-ligation and enhancing the bonding and debonding characteristics of the bracket.

- 3. Intended Use :
The device is intended for orthodontic movement of teeth. It is used temporarily and is removed after orthodontic treatment has been completed. The devices are intended to be single used only.

- 4. Technological Characteristics:
The MACH BRACKETS is produced using Al2O3, translucent polycrystalline aluminum oxide (99.99%).

This MACH BRACKETS are bonded to the teeth with commercially available materials and linked together by "arch wire" that applies steady, gentle produce desired tooth movement

- 5. Performance: Bench tests were performed.
